Title: Devices for feeding sheets to calender and the like machines
IPC: D06C3/00
Filed: 1957-04-18
Abstract: 829,928. Ironing-machine feed. WOMERSLEY, A. E., and KELLETT, H. April 14, 1958 [April 18, 1957], No. 12636/57. Class 138 (2). [Also in Group XVI] A sheet of rectangular material to be fed towards rolls 11 of e.g. an ironing or calendering machine, is placed over the framework of Fig. 1 with the extremes of its leading edge in clamps 2 slidable along a bar 4 of the frame 8 which is pivoted at 10 and normally biased to the position shown by a weight 5. An hydraulically operated piston 44 acts upon a pivoted bar 40 to move the carriage 30 along bar 32 (towards the left in Figs. 1 and 2) and actuate pivoted parallel linkages 26, 28 so as to separate the clamps 2 until the material leading edge is taut. At this stage separation of the clamps ceases, and continued movement of carriage 30 tilts the frame 8 forwardly about pivots 10 to present the leading edge, which is slightly proud of the front edges of the clamps, to the bight between the rolls 11. The weight of material when placed in position actuates micro-switches 50 and 52 (not shown) in the clamps, to close an electric circuit (Fig. 5, not shown) and open valves which admit pressure fluid to cylinders 24 to close the jaws 14, 16 and grip the sheet. Simultaneously a further valve is opened to admit fluid to the cylinder 46 to cause piston 44 to move inwardly and actuate the carriage 30 &c. At the end of its forward pivotal movement the frame 8 actuates a switch element 61 to interrupt the fluid supply to cylinder 46, whilst another switch element 63 also closes to interrupt the supply to cylinders 24 thus opening clamps 2 and permitting feed of the sheet. When the trailing edge of the sheet passes over switch 50 the latter returns to its normal position, and since switch element 63 is closed fluid is now admitted to the opposite end of cylinder 46 to move the piston 44 outwardly to restore the carriage 30 &c. to the position of Fig. 1, and the switch elements 61, 63 to their normal positions. Registration control.-The sheet is maintained straight and parallel to the rolls 11 by a photoelectric cell and a light source provided in each clamp, between which the side edge of the sheet must pass. If the sheet is displaced to expose the cell to the source a solenoid-controlled valve in the pressure fluid circuit operates an hydraulic motor 70 coaxial with and driving a tensioned roller 72 over which the sheet is draped. The transverse force exerted on the sheet by the rotation of roller 72 re-aligns the sheet. The edge of the sheet also now intercepts the light from the source and motor 70 stops.

[Class 112.] An additional movement is given to the feed of a book-stitching machine, in the absence of a signature on the work-table in order to position the stitching on the succeeding signature. The feed is actuated by a lever 21. The normal movement is provided by a cam actuated lever 8 and an adjustable link 18. The additional movement is provided by a cam 24 which is coupled to a driving disc 13 by a spring pressed lever 30. The coupling is controlled by a fixed disc 17 and a flap 33. The flap is actuated to permit the coupling of the cam 24 and disc 13 by a signature engaging arm 45 and linkage 41, 40, 38. While the arm 45 is resting on a signature the flap prevents the coupling. The arms 45 is raised by a cam actuated lever 50.

Abstract: 253,852. British Tabulating Machine Co., Ltd., (Tabulating Machine Co.). Feb. 17, 1925. Cash registers ; printing and perforating mechanism.-In a cash register or other keyboard machine adapted to record transactions, a bank of keys is provided for the purpose of recording the names of the commodities. As shown applied to the machine described in Specification 253,569, depression of any of these keys rocks a corresponding shaft so as to permit the descent of a removable frame comprising a number of fingers 309 having lugs 310 to enter the path of pins 319 on bars 318. In the operation of the machine the bars are released, and those unobstructed by the pins move to the right under the action of springs 320 and by means of levers 322 position corresponding pin-bars 324. The type sectors 261<a> each carry type for the digits and the alphabet, and when freed by a yoke descend to an extent depending upon the position of levers 263, 263<a>. The lever 263 co-operates with steps 264<a> on the type sector and is mounted upon a pivoted sector 326 so that its controlling effect is dependent not only upon the angular movement imparted to it by the pin-bars 324 but also upon the position of the sector 326. The latter is in turn controlled by the lever 263a which selectively engages steps 325 on sector 326, is moved by the pins on bars 324, and is mounted on a sector 382a having a shouldered slot 831 to co-operate with pins 324b on the bars. The punches 115 for perforating the audit card are controlled by the right-hand ends of the bars 318 through stop-plungers 330. To introduce a further variation in the setting of the bars 324, the two lowest may have a pin-and-slot interconnection so that according as one or both are free to move so any step from one to three may be given to the lever 263. The control frame or comb 308 may take the form of a box 312 with removable and interchangeable fingers 309<a>, and for economy of space the lugs on these may lie in planes parallel to the bars 318 instead of at right-angles to them.

Title: Improvements relating to weighing and packing machines for powdered, granular and other like materials
IPC: G01G13/00
Filed: 1926-05-21
Abstract: 272,028. Berkshire Printing Co., Ltd., Brooke, N., and Ballard, R. May 21, 1926. Apparatus fitted to packing machines.-In an automatic weighing and packing machine, the action of the weighing machine part is co-ordinated with that of the packing-machine part by arranging two automatic switches in the circuit controlling the weighing machine, the first switch being actuated upon the delivery of a charge from the weighing machine, and the second upon the delivery of a charge from a checkweighing pan to the packing machine. An application to a tea packing machine according to Specification 262,550, [Class 94 (i), Packing &c.], is described. Associated with an annular series of rotatable hoppers a, check-weighing pans i, and funnels k leading to paper bag holders u, is an automatic weighing b the electromagnetic operation of which is controlled by a circuit 6 having switches g, 4. The switch g is adapted to be closed by a counterweight h, Fig. 3, engaging a spring strip f. When a charge of tea is delivered from the weighing machine through the passage d, a flap e is caused to fall and moves the counterweight to open the switch, which remains open until an arm j is thrown over by one of a number of tappets i carried by the rotary systern. From a hopper c the weighed material passes to a rotary hopper a and thence to a check weigh-pan l balanced by a weight 7. The pan l has a hinged bottom m which is normally held closed by a spring blade p on a spring-wedged arm q bearing upon an arm o. At a definite point in the rotation of the packing system, the arm o is released by a cam t engaging a slider s which bears upon the lever q. If the weight of material in the pan l is not excessive, the pan rises, the bottom m passes a fixed stop n, and the contents are discharged into the hopper k. At the same time a slide 2 is pushed out and engages an arm 3 to close the second switch 4 in the weighing machine control circuit, thus permitting the weighing machine b to function again. If the weight in the pan l is excessive, the weighing machine is stopped, and it is also stopped if no bag has been placed on the holder u, by an arm y engaging a catch z on the pan l. A feeler w connected with the arm y bears upon the bag. The switch operating slide 2 is engaged by a fixed abutment 5 to return it to normal position. More than one weighing machine may be combined with one packing machine.

In a jigging conveyer tube 1 along which material is conveyed a discharge aperture 2 is controlled by a discharge slide 4 which is operated by handle 25. The slide 4 carries side members 19 which slide on supports 20 resiliently mounted at 22. Handle 25 pivots at 17 and is connected to the slide through arms 6, and the movement of the handle and therefore of the slide is governed by toggle members 15, 16 pivoted between 7 and 14 and connected together at 17 so that movement of the handle 25 clockwise about pivot 7 causes a quick movement of slide 4 in its closing movement. The movement of the slide is quicker than that of the conveyance of material along tube 1, which fact tends to avoid any hindrance of the movement of the slide by the material conveyed. Alternatively, the movement of the slide may be effected at this speed by fluid cylinder 28.
